Assuming the tech support centers aren't as fully staffed on Sunday as they would be on Monday; I wonder if they decided to drop it on a Monday since it is a whole new OS, and not just a revision? I'm sure they will be flooded with questions such as "My media thingy used to be an app, now it's just a folder....... WTF?"

Yeah, plus it won't be available for download OTA either. So maybe that has something to do with it?

Could be. Maybe they just felt the need to have more techs on-hand to walk people through the DM update process. I get a feeling that a lot of non-enthusiast users who might still be running 4.7.0.x with DM 4.7 are going to need help - since IIRC 5.0 OSes won't install on DM 4.7

Where's the leak??? I thought we would see this one before the masses!!

Yup, and the weekend ain't over yet, either.

(Not saying it will or won't, I have no idea. But we JUST got .323; we'll either see .328 within the next 48 hours, or once it's official - either way, it's a short time anyways. Enjoy your weekend and don't worry about a build only 5 higher than what we've got, IMHO)
